Heating an d hot water p i p ing installation
40
Failure to use the insulation flange may cause
rapid corrosion (rusty water). We do not take the
responsibility of the problems arising from failure
to use the insulation flange.
Be sure to use the insulation flange on
the heating inlet and outlet in case of
installation of the copper pipe.
(the hot water inlet and outlet for a
boiler dedicated for hot water supply)
Do not exert excessive force on the pipe during the
installation. Damages on the parts may cause a water leak.
Fix the parts of the boiler pipes with
appropriate tools, prior to piping installation.
The exposed pipes may get frozen in the winter.
If the water supply pipe is frozen, the hot water is not
supplied, and when the heating pipe has run out of
water, the water is not supplemented. Consequently,
the boiler can not operate normally.
The exposed pipes shall be heat insulated
with the insulation material.
Salt content in the sea water or spa water may accelerate
corrosion and shorten the life of the boiler.
We do not take the responsibility of the problems caused
by using water, other than the tap water.
Do not use water, other than the tap water,
for the boiler.
